Corresponding simultaneous resistivity data/piezo voltages/capacitance are in file:
Data/Birefringence_Data/FeSe_Warmup1_20211014_20x/FeSe_20211014_50K_StrainLoop1/FeSe_20211014_50K_StrainLoop1_BirefRes.txt
Each row of data maps sequentially to the corresponding image number.

Images for all strains are autocorrelated for spatial overlap and images are normalized by the fully detwinned reference image ('0') as a background. Plotted images are on '50' (0.00%) and '100' (0.22%) after background normalization.

Images are processed by the same method for 20x images as described above. 

Corresponding simultaneous resistivity data/piezo voltages/capacitance are in file:

Each row of data maps sequentially to the corresponding image number.

Similar data for each temperature <= 90 K are provided in corresponding subdirectorys in folder: Data/Birefringence_Data/FeSe_Warmup3_20211020_50x/

Inside individual temperature folders, resistance data are from files of the form
'Fese_20211020_TEMPK_StrainLoop2_BirefRes.txt' (T <= 90 K)
'FeSe_20211020_TEMPK_StrainLoop2_Res.txt' (T > 90 K)
For temperatures 30 -> 120 K in 5K steps
